Boss Lowdown and That Juicy Lore

Picture this: Dahlia, 5★ Fire Nihility Super Break support, hitting Phase 1 from Dec 16/17 to Jan 6/7, 2025. At Lv80, she's packing ATK 679, DEF 606, HP 1086, SPD 96, Energy 130, plus traces bumping +37.3% BE/+18% Effect RES/+10% HP. Sushang ramps her from 8k DMG to 23k Super Break on Swarm Floor 15. Yeah, prioritize ≥250% BE/≥145 SPD—it's non-negotiable.

Hoard 3,887,800 Credits/Ore for Lv80 and traces. Don't sleep on it—stockpiling now means you're bursting on drop day.

Breaking Down Her Core Mechanics

How She Attacks and Phases Out

Her Skill? 160% ATK Fire Blast plus a 3-turn Zone cranking +50% ally BE, converting TR to Super Break DMG. Ult slams 300% ATK Fire AoE (120 Energy), slapping a 4-turn Wilt for -18% DEF and a Fire Weakness implant. Talent feeds +35 Energy to your DP; if broken, it's 60% Super Break DMG—otherwise, 5x 30% ATK Fire FUAs (200% Super Break each on broken states, 1/turn). Play it like: 1. Keep that Skill Zone rolling. 2. Ult for Weakness and DEF shred. 3. Talent FUAs on unbroken foes.

Elemental Edges and Resistances

Bonus 3 unlocks Fire Weakness (20 TR/+10% Energy, caps at 50%). Bonus 1 kicks off with +24% ally BE/+50% self BE (1 turn, retriggers on heal/shield). Bonus 2? +1 SP per 2 FUAs. Ult drops TR from 30 to 20; Bonus 3 adds 20 TR/Weakness. That implant? Pre-Break, it pumps +40% BE for Fire teams.

Ever-Flame Mansion's Nasty Arena Tricks

Zone boosts +50% BE; unbroken TR flips straight to Super Break. Her E2 Wilt? All-Type RES-20% across the board. Dropping to 140% BE bloats Swarm clears to 51s. Hit ≥145 SPD on Feet—substats? BE > SPD > ATK, every time.

Building Your Squad Right

Roles: DPS, Sustain, Buffer Breakdown

Stats across the board: Body HP%/DEF%/EHR; Feet SPD≥145; Sphere HP%/DEF%; Rope BE%/ERR; subs BE > SPD > HP%/DEF%. Firefly's Ult? +100% advance/+60 SPD/+50% BE/+20% Break DMG. Combustion layers +10% Energy/Fire Weakness (50% cap).

DPS picks: Firefly/Boothill/Rappa.
Sustain: Lingsha edges Gallagher (+25% Break DMG/100% Action Forward).
Buffer: Harmony TB > Bronya/Pela; Dahlia stays SP-positive with her sig LC.

Synergy That Makes Dahlia Shine

E0S1 Firefly+Dahlia outperforms higher E idols without her. Fugue shreds Toughness/CC; Ruan's Ult stretches Zone to 7 turns. Stack 237% BE with sig + Ruan. Flow: 1. DP grabs +35 Energy. 2. Fire Weakness at 20 TR. 3. Ult/Skill for DEF shred.

Pitfalls and Quick Fixes

Timing Blunders

Skip CRIT—BE/TR scales harder. ≥145 SPD locks Zone; Ruan hits 7 turns. 1. Weekly 90 TB. 2. Cavern Path of Drifting (+50% drops).

Element Mismatches

Dahlia > Ruan for Super Break; Lingsha > Gallagher. Firefly's multi-hits shred. E0S1 > higher E without Dahlia. (Editor's take: Data shows it—pure numbers.)
